Infusionsballonkatheter mit Flechtwerk

摘要

This is a perfusion catheter having an inflatable membrane or balloon located at the distal end of the catheter shaft. The shaft is comprised of an outer tubing assembly and an inner tubing assembly separated by an open annulus for inflating and deflating the inflatable membrane. The outer tubing assembly is made up of at least one polymeric layer and a super-elastic braid. The inner tubing assembly is made up of one or more layers of polymeric tubing, the innermost of which is preferably a very lubricious polymer. The outer tubing assembly allows the profile of the catheter to be minimized and yet provides significant kink-resistance to the inner tubing assembly.
